Popis: | A sonochemical method by using various time and concentrations of initial reagents and power of irradiation, was used to synthesize nano-card house of a new copper(II) metal-organic coordination system, {[Cu2(p-2yeinh)2Cl2]·(H2O)}n (1), where p-2yeinh = pyridin-2-yl ethylidene-isonicotinohydrazide. The compound was characterized by scanning electron microscopy (SEM), elemental analysis, IR spectroscopy, X-ray powder diffraction (XPRD), and single crystal X-ray analysis. The X-ray structure revealed that the Cu(II) atom is coordinated by one oxygen and three nitrogen atoms from two p-2yeinh ligands and one chloride anion with a CuN3OCl donor set with square pyramid geometry. This arrangement produces a large quadric nuclear square ring composed of four square pyramid Cu(II) moieties linked together by two p-2yeinh units (M4L4). The adjacent frameworks connected by strong hydrogen bonding interactions of methanol molecules that interact together and with the rings and π–π interactions of adjacent aromatic rings of p-2yeinh and other weak interactions. Consequently, the labile interactions also allow the discrete structure to form a 3D metal-organic coordination network. CuO nanoparticles were obtained by thermolysis of 1 at 180 °C with oleic acid as a surfactant. The average diameter of the nanoparticles was estimated by XPRD to be 38 nm. The morphology and size of the prepared CuO nanoparticles were further studied using SEM. |
